Patented Dec. 3. 1907.

' Application tiled December 24] 1904- Serial mi, 238304- Transmitting Mechanism; and Ihereby declare the following to be a full, clear, and

exact. description of the invention; such as will enable others skilledinthe art; to which it pertains toznal-ze and use the same.

lhis invention relates to improvements in self-propelled vehicles, and especially-to power transmitting mechanism therefor.

.The object of this invention is to provide 1 mea'nsfor utilizing the'cnergy'of an explosive 'viding new and improved means for coupling.

engine or other rapidly operating engine in an economical 'inannerend with the highest eiliciency. Q.

My invention,' therefore, consists in ro;

the engine with'the driving wheels of the car-l My invention also consists inthe features of construction and combination of parts as.

described in the specification, pointed out in the claims and illustrated in the drawings.

In the. accompanying drawings, Figure 1- Shows a top plan of a car embed 'ng my in- .vention with the body portion 0 the'car-removed.- Fig. 2 is a. side elevation of same with part broken away andportions in section. Fig. 3. is a section on line 33, Fig.2. Fig. 4 is a. section on line 44, Fig. 3.

Again referring to the drawings, 1 represents the frame of the running gear. In this frame are mounted, in .the usual manner, front and .rear axles, 2 and 3 respectively.

On the front axleare mounted traction a wheels 4, and on the rear axle are mounted .fion. The engine 7 traction wheelsfi. On the front part of the frame 1 is arranged'a platform 6, on which is mounted an engine 7, of the usual'construcis provided nivith the usual engine shaft 8 on which is rigidly secured ahslance wheel 9 and a gear wheel 10.

'Supports 11' are arranged to extend back from theplatform 6, andon these supports the gear wheel on the engine shaft 7.

are formed bearings 13 for a shaft 14.

wheel 15. A gear wheel 16.15 also secured on the shaft'14 and is arranged to mesh with each wheel 15 is rotatably secured a crank pin 17, which has an enlarged head or box 18,

On' each end of the shaft 14 is rigidly secured a.

preferably, formed integral therewith. .In

this head or box isfOrmed an opening 19 jacentthcreto. On the other end of each ofthe'levers 22 is arran ed a sliding extension.

orslee-ve' 24, and on the sides of each of the said extensions '24 are arranged curved lugs .25 and 26," on the sup ortare mounted two brackets 27, on eac hof which isivetally mounteda'n arm 28. One-end or each arm 28 extends between the lugs 25 and 26 on the extension 24 adjacent thereto, and to V the opposite end thereof is secured a link 29; The links 29 are in turn pivotally secured to a red 30, which is pivotally-connected with a i hand lever 31 J fulcrumed on a support 32 se-" curcdgin frame 1'. Lockin means of the usual construction are provided for; holding the hand lever 31 in any position in which it is placed, and this locking means 'c omprises' a serrated sector-shaped plate 33, which is rigidly secured to the sup ort 32. A spring controlled latch 34 is slidably mounted on the hand lever 31 and is arranged torengage with the teeth on the plate 33. I

On the axle '3 are rotatahly mounted two drums 40. Within the'flange of each drum 40 is arranged a clutch disk 41', which is keyed to the. axle 3. In the perimeter of each disk 41 are formed a series of pockets 42, the sides of which are inclined and converge at the bottom. In each pocket 42 is arranged a ball 43; the diameter of which issuch that when said ball is in thedeepest tatedin one direction, that is to the'right asshown in the drawn the ballswill move the respective pockets, but when the drum is turned .in the opposite direction, that is The operation of towardsand remain in the deepest part of t 2 5 .aoon ss'the drum begins to move in the direc-- 2 a I was towards the left, the balls will be forced into the more shallow parts of the respective pockets; and will consequently wedge between the drum and the disk, thereby lock- 5 ing the drum to the disk and consequently prbventinq the drum from turning on the axle cable 47 of'sufiicientlength to allow a partial "turn around the drum 12 secured at oneend .to each' drum 40, and the' other end is secured to the outer; end of the' extension 24 on the end of the adjacent lever '12. A coil spring 48'is secured to each drum 40 by means of a pin 49, and to the frame of the machine by means of a pin 50. Y 1 15 The operation of my improved power transmitting mechanism is as follows:- When the engine is started, ,the' wheels 15 are caused to rotate through their operative connection with the engine, and as they rotate they impart a vertical. reciprocatingmo'tion tothe levers 22. As the forward end of the lever moves down, the rear end moves up .dr"Wing the cablafrom the drum, and thereby c.- "sing a rotation of said drum, and as tion it is rotated by the movement of the lever, it is locked to the axle by means of the clutch.' When the forward end of the lever moves up, then the rear end will move down 80 and the spring which is secured to the drum will cause a rotation of the drum in the opposite direction to that in which it. was rotated by the movement of the lever, and the cable will'iie again wound on the drum. If it is at desired to decrease the speed of the machine, the hand lever is pulled backwards which shoves back the rod and the links 29, thereby causing the ends of the arms 28 4 which are connected with said links to swing back, while the other ends of said arms which extend between the curved lu on the extension 24 are caused to swing orward shoving the extension up on the ends of the levers 22 .thereb shaft, a cable connecti decreas the length of said levers an comapo iidingly decreasing the speed of the machine. Likewise if it is desired to increase the speed of the machine, the hand lever is moved forward, increasing the length of said levers 22 and causing a corresponding increase in the speed of the machine. The curvature of the lugs 25 and 26 permit the ends of the arms 28 to remain in operative connection with the extension 24 at all times.

What I claim is:

Power transmitting mechanism comprisiiig, the combination of a-frame, an engine mounted on said frame, a gear wheel secured on the engine shaft, a shaft arranged at a right-an le to the engine shaft, a gear wheel mounts on said last-mentioned shaft and arranged to mesh with the gearwheel on the engine shaft, two wheels rigidly secured on said last-mentioned shaft, boxes rotatably mounted on said wheels, levers fulerumed in said frame and having their ends extending into and arranged to slide freely in the respective boxes, sleeves arranged on the oppo-.

site ends of said levers, means for sliding said sleeves in and out on same, means for locking said sleeves 1n their ad1usted positions, a

driving shaft, .drums mounted on said eachdlum with one of saiddevers so that t e movement of said levers in one direction Wlll cause a rotary -movement ofsaid drums in one direction,

automatically operating clutches arranged to 1 lock said drums to said driving shaft when said drmns are rotated by the movements of.

said levers, and springs for rotat' said drums in the opposite direction to t at in Wl'llCh they were rotated by said levers, substantially as described and for the purpose set forth.

In testimony whereof, I sign the foregoing specificationflnthe resence of two witnesses.
